| description | Improved knowledge of nutrient removals from harvesting is essential for the sustainable management of Moso bamboo forests. In particular, the growth and development of bamboo forests are considered to meet the increasing demand for biomass energy. In this study, plots with an 8 m width strip cut (SC) after five years of restoration were selected as the research object and the traditional management forest (CK) as the control. The nutrient content and biomass of Moso bamboo at different ages were studied and the nutrient storage was calculated. The results showed that five years after cutting, the soil nutrient content in different soil layers and the aboveground nutrient storage reached the same level as the CK. The nutrient ranking of each organ of Moso bamboo was nitrogen > potassium > phosphorus. The phosphorus content of bamboo culm in CK was significantly higher than that in SC at different ages (<i>p</i> < 0.05). The biomass accumulation of each organ of Moso bamboo was culm > branch > leaf. In addition, the relationship between nutrient storage and DBH and density in SC is a simple power form, and the coefficient of determination of most computational models is above 0.9. Our results demonstrated that strip cutting is more economical than traditional management, but nutrient addition is needed to improve the quality of new bamboo trees at the initial stage of recovery in consideration of long-term productivity maintenance. |
